While this has not been released by LSAC, we took our best shot. To quote our outstanding statisticians on the methodology:
We took an average of the minimum number of correct answers needed for a certain score in the last 3 years, and then multiplied that by 75/100.78 … i.e., [75 expected Qs on LSAT Flex (23 LG + 27 RC + 25 LR) / 100.78 (the average # of Qs per PrepTest the last 3 years)]. Then, we rounded those figures to their nearest integer and started assigning numbers from 180 down. If a number was already used, then that scaled score was unscorable.
While this cannot be used to perfectly calculate your score yet—as the official scale has not been released—by adding up the number of correct answers of your Logic Games, Reading Comprehension and average Logical Reasoning performance on a given PrepTest, you should expect a score similar to what you’ll see in the table we’ve put together.
